Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized electro-optic retroreflection scanning mode equipped with all necessary components and a completely built-in type. SOLUTION: This retroreflection scanning module is equipped with a base part, a 1st circuit board 416, and a 2nd circuit board 418 which is fitted almost at right angles to the 1st circuit board 416. The base part supports a light radiation body, which generates a scanning beam and an optical component which directs and converges light energy. A radiated beam reflection body reflects the light from a return mirror 212 on a reflection body fitted to a drive part for an oscillation body. The reflection body changes the direction of the beam to a mark to be read. The mark is scanned with the beam through the vibration of the reflection body. The reflected light is directed to the vibrating reflection body and made incident on a converging mirror 204, before reaching a detector 206. The detector 206 included in the module detects the light reflected from the mark scanned with the beam. The beam and the visual field of the detector 206 are scanned at the same time. Various implementation styles of vibration drive and optical arrangement are disclosed to make the scanning module small-sized.

Abstract: An electro-optical, retroreflective scanning module has a base, a first circuit board, and a second circuit board mounted orthogonal to the first circuit board. The base supports a light emitter for producing a scanning beam. The beam reflects off a generally planar scan mirror affixed to a stationary concave collection mirror, to a reflector mounted on a drive for oscillation. A detector included in the module senses light reflected from an indicia scanned by the beam. The reflected light is reflected off the reflector and directed to the collection mirror before reaching the detector. The beam and the field of view of the detector are simultaneously scanned.
